We loved our stay at Kanit's apartmet! The location is a minute away from the BTS (the green line that can take you to most tourist hotspots) and has a variety of food outlets nearby (budget and moderate). The place was sparkling clean (infact better than the photos) and honestly surpassed our expectations. It is located in a new building which has a pool and a gym which you can use as well (we didn't get the chance to try it though).
A special mention must be made for Kanit, our host. He was super helpful and responsive, and while I didn't get a chance to meet him, I always felt like he was only a minute away if I needed any help. The proof of the pudding in any business lies in whether the customer is willing to come back, and we would be more than happy to stay at Kanit's place when we go back to BKK (which we will, love the city!). It's an effective, economical, convenient place with a wonderful host to go with it!
If you're a family of 2/3, close your eyes and go ahead and book, I am certain you won't be disappointed!
